Circulating Immune Complexes in Acute Uveitis: A Possible Association with the Histocompatibility Complex Locus Antigen B27

摘要

39 patients with acute anterior uveitis were investigated for the presence of circulating immune complexes (IC) and correlation with the major histocompatibility complex antigen B27 (HLA–B27). ICs were demonstrated by a number of techniques including rheumatoid factor, complement (C) activation, anticomplementary activity, cryoglobulins, inhibition of IgG–EA rosette formation and neutrophil chemotactic index (NCI) in plasma. ICs were most frequently detected in HLA-B27-negative patients. These results indicate that deposition of circulating ICs may be involved in the pathogenesis of acute anterior uveitis, especially in HLA-B27-negative patie
